What is the current behavior?

ThemedSider doesn’t consistently honor the Title override. When Title is provided as a render prop or element, the default title may still render.

What is the new behavior?

If Title is provided, it is always rendered (supports component, render prop, or element) and the default title is only used when no override is provided.

Hey @harsha-cpp, thanks for the PR!

The Title prop is typed as React.FC, so it only accepts function components. The existing code const RenderToTitle = TitleFromProps ?? DefaultTitle already handles this correctly — if Title is provided it's used, otherwise the default kicks in. The isValidElement / ReactNode branches in renderTitle handle cases the type system doesn't even allow.

Also, the changeset is marked as major but there's no breaking change here. I wasn't able to reproduce #7239 either. Closing this one — thanks for looking into it!
